Patented July 7, 1936 UNITED STATES PATENT OFFICE WINDOW OPERATING AND ADJUSTING MECHANISM 2 Claims.

My invention relates to improvements in window operating and adjusting mechanism, and particularly to a structure of this character intended and adapted for use upon casement windows, French windows, and other hinged windows or closures.

An object of my invention is to provide a de-- vice that can be completely and readily installed for use, and with which the window can be opened, closed, and adjusted to any desired posi-- tion of opening, with facility and with a minimum expenditure of energy.

Another object is to provide a device which can be used with double swung windows, such as for instance French windows and the like, and which is so constructed that one adjuster operates both windows at the same time, and serves to rigidly hold the windows in any desired adjustment and in closed positions.

Yet another object is to provide a mechanism by which the window is held, braced and secured on its outer rail, and throughout substantially its entire height, thereby eliminating the usual unbalanced connection of window adjusters as heretofore used, and insuring that the window will be completely and firmly braced and held against racking, twisting, and pulling loose from its fastenings due to force exerted in the actuation of the operating mechanism, through the force of the wind, or through other causes.

Still another object is to so construct the parts that, when used with a pair of double swung'win dows, the two windows will be properly held and r braced when in the open position, and will be secured and rigidly locked in the closed position, thus securing the windows against being accidentally or casually moved by the wind, and against being opened from the Qutside'm'aking the window burglar proof in that respect.

With these and other objects in view, which will be apparent to those skilled in the art, my present invention embraces certain novel features of construction and combinations of parts which will be hereinafter more fully set forth in connection with the drawings and then pointed out in the claims.

In the drawings:

Figure 1 is a view in elevation taken from the r inside of a pair of windows having my invention applied thereto.

Fig. 2 is a transverse vertical sectional view through the window structure thus equipped.

Fig. 3 is an enlarged fragmentary elevational view to better show the operating mechanism.

Fig. 4 is a fragmentary view taken substantially at right angles to the showing in Fig. 3, and with parts in section to more clearly illustrate the construction and operation.

Fig. 5 is a fragmentary detail view illustrating a swivel connection of one of the operating rods. The two window sashesv or frames l and 2 are hinged in the usual manner within the casing or frame 3, and the sash will open outwardly from the center of the frame, the inner rails 4 and 5 of the two sashes l and 2 being formed to fit together in proper'relation when the two sashes are closed.

To all intents and purposes, the two sashes are hinged in the usual and ordinary manner, and in fact these might be two'window sashes that are already in place and to which the device of my invention is to be applied. Further, while I have shown the inner rails 4 and 5 of the sashes adapted to close one against the other, my invention is adaptable for'use where the two sashes are separated by a mullion; and, it will be apparent that various other forms and types of windows'can be fitted with myimproved window operating and adjusting mechanism.

Slide rods 6 and 1 are mounted 'in substantially vertical relation to extend along the middle portion of the rails land 5 o f'the sashes l andi, and these rodsare rigidly held in brackets '8 and 9 so that the rods are'slightly spaced from the rails of the sash. The-ends of the rods Wand"! can be fitted in appropriate openings in the bracket members 8 and 9, or these parts can be assembled in any other desired and suitable manner that will insure a rigid and permanent securement of the ends of the'rods 6 and l, when the bracket members 8 and Bare secured in place upon the rails 4 and 5, by means of screws or other suitable fastenings. 1

A supporting case IQ is mounted centrally upon the window sill II, or at some other appropriate point on the lower part of the window frame or the supporting structure therefor, and this casing in has a shaft I2 journalled revolubly therein in substantially horizontal relation with one end projecting and terminating in a crank or winding handle l3 thus positioned to be available from the inner side of the window. The shaft 12 has a worm l 4 thereon within the case, and this worm is rotated through the medium of the handle I3. A worm gear l5-is osciilatably mounted within the case l0 upon shaft I 6 and is in mesh with the worm l4, so that as the operating crank i3 is manipulated the worm gear 15 will be oscillated within the case.

This worm gear l5 has a mounting stud or arm I! extending therefrom to swing within slot; l8 formed in the upper part of case I0, and this mounting stud or arm I! is bifurcated to receive and hold a segment bearing plate l9, rigidly connected with the stud or arm I! by riveting, or in any other suitable manner.

Operating arms 20 and 2| are bifurcated to fit freely over the bearing plate l9, and are pivotally connected with the plate at 22. With this mounting of the operating arms 20 and 2|, these arms are free to swing laterally in a plane parallel with the flat sides of bearing plate l9, but are absolutely held against twisting or shifting forwardly and back.

Slide bearings 23 and 24 are mounted on slide rods 6 and l to be freely movable along the length thereof, and yet to preferably have a suiiiciently tight fit to prevent twisting and rattling of the parts. These slide bearings have bearing ears 25 formed to receive the bearing ends 26 of the operating rods or arms 20 and 2|, and it is perhaps desirable that the bearing portions 29 of these arms or rods 20 and 2| be made swivelled after the manner illustrated in Fig. 5, so that twisting and strain upon the slide bearings and the operating rods or arms will be avoided. As illustrated in Fig. 5, the pins 21 mount the bearing portions 26 for swivelling movement on the ends of rods or arms 20 and 2|.

The casing l can be mounted and secured in place by the use of screws or other suitable fastenings, and with the parts assembled and mounted in the manner set forth, as handle I3 is manipulated to rotatashaft l2 and consequently worm M, the plate l9 will be swung forwardly or back, substantially between the extremes shown by the dotted and the full lines if Figs. 2 and 4. As the plate I9 is swung, the operating rods or arms 20 and 2| are carried therewith, and the slide bearings 23 and 24 are lowered along the rods 6 and 1, which causes the window sashes and 2 to be swung outwardly, the rods 20 and 2| spreading angularly outwardly at their outer ends, substantially as indicated by the dotted lines in Figure 1.

Due to the fact that the slide bearings 23 and 24 are mounted on slide rods 6 and I, and these slide rods 6 and I extend substantially throughout the greater portion of the length of the inner rails 4 and 5 of the swinging sashes and 2, irrespective of where the bearing, members 23 and 24 may be along the length of the rods 6 and 1, the window sashes will nevertheless have the force to move or hold the same applied substantially through the bracket portions 8 and 9. Consequently the strain of force exerted upon the sash is substantially equally and evenly distributed and is spread over a great extent of the swinging edge of each sash, being substantially equalized upon the entire sash structure and upon the hinges carrying the sash. Further, due to the fact that the rods 6 and I are on the other rails of the swinging sashes, the sash is held with substantially uniform force and security at both its hinged and its swinging edges.

In opening and closing the sash the force is applied substantially uniformly throughout the entire sash structure, and any strains due to wind force or the like are similarly distributed and equalized. When it is desired to close and secure the sashes, the handle I3 is manipulated to move the parts to substantially the relation shown in Figs. 2 and 4, and the rods 20 and 2| then pull in on the slide rods 6 and and se- 5 curely hold the sashes and 2 against being opened. The worm I4 securely locks worm gear l5 against rotation by force exerted in any other manner than by manipulation of handle I3, and in consequence the window sashes are securely 10 and rigidly held in any adjusted position, and are positively and absolutely locked when brought to the closed positions.

While I have herein shown and described only certain specific embodiments, constructions, arrangements and mountings of the parts, and have suggested only certain possible modifications in use, it will be appreciated that many changes and variations can be made without departing from the spirit and scope of my invention.
